In a medium mixing bowl, combine warm water, sugar, and instant yeast. Let it sit for about 5 minutes until frothy.

Add all-purpose flour and salt to the bowl. Drizzle in olive oil or melted butter, mixing until a soft, shaggy dough forms.

Turn the dough out onto a floured surface and shape it into a rough loaf. Place on a parchment-lined baking sheet.

Let the loaf rest for 5 minutes while preheating your oven to 400°F.

Brush the loaf with olive oil or melted butter for flavor and sheen.

Bake in the preheated oven for about 15 minutes, until golden brown and sounds hollow when tapped.

Remove from oven, let cool on a wire rack, then slice and serve warm.
